Design and analysis of a linear oscillatory actuator for active control engine mounts

摘要

A linear oscillatory actuator (LOA) for active control engine mounts (ACMs) is proposed in this paper. This LOA performs high thrust characteristics using a small size mover. Static and dynamic characteristics are computed through a coupled method of magnetic field and motion analyses employing 2-D finite element method. In addition, the effectiveness of proposed LOA is verified by the comparison with our previous LOA. In order to verify the applicability for an ACM system, vibration reductions using a least mean square adaptive filter are clarified.
